I had a Husqvarna lawn edger attachment that broke during the warranty period. After a back and forth with customer service, their only solution for me was to bring to an "Authorized repair center". I would have no problem with that if there wasn't a diagnostic fee, that would be waived if the repair was going to be covered under warranty, or I would have to pay if it was not. The potential fee was $50 on a $100 item. The thing is I could literally hold the broken part in my hand and say "this is what is broken, here is the part number, is it covered?". They could not answer that unless the repair center looked at it. It is a known issue with the flex shaft that many people have documented online. Husq doesn't care, in fact most of their twitter feed is filled with customer complaints.
Credit Card warranty couldn't help because it was within manufacturer's warranty.
I got the Attn. General involved who basically arbitrated the conversation, ultimately did not help one bit. I even cited the Magnuson-Moss Warranty Act mentioned here by the FTC.
This has re-invigorated me to try going down the FTC complaint route. It's not about the $100 now, it's about Husq standing behind their products and fixing known issues, and not lying to consumers with BS warranties on the box.
Not helping my case: I bought another one because the attachment is basically the best on the market. I fully expect the same thing will happen again, armed myself with a better 3rd party warranty this time. I hope it at least makes it through 1 season.
